1(A). A centrifuge in a biology laboratory rotates at an angular speed of 3,550 rev/min. When switched off, it rotates 50.0 times before coming to rest. Find the constant angular acceleration of the centrifuge (in rad/s2). Consider the direction of the initial angular velocity to be the positive direction, and include the appropriate sign in your result.  rad/s2   (B) The tub of a washing machine goes into its spin cycle, starting from rest and gaining angular speed steadily for 6.00 s, at which time it is turning at 4.00 rev/s. At this point, the lid of the washing machine is opened, and a safety switch turns it off. The tub then smoothly slows to rest in 13.0 s. Through how many revolutions does the tub rotate while it is in motion?  rev
